Professor X

Professor X asks a girl, "what is your mutant power?"

Girl replies: "I can guess how many pulls to turn a ceiling fan off on the first try!"

She points up and says: "3 pulls"

Professor X stands up and pulls 3 times. After the third pull the fan turns off.

Professor X: "Yeah that's cool and all, but not really a super power..."

Girl: "Yeah I was jut kidding, I can heal paraplegics"

Professor X, still standing: "OH. MY. GODDD !!!!"

Professor X: what's your super power?

Me: hindsight

Professor X: that's not going to help us

Me: yes I see that now
